Abstracts

Background: Polyscias fruticosa is been used in Ghanaian folkloric medicine for the management of asthma and its related complications.

Aim: This study evaluated the muco-suppressant, anti-tussive, and safety profile of an ethanolic leaf extract of Polyscias fruticosa in its use as an anti-asthmatic.

Place and Duration of Study: Department of Pharmacology, Faculty of Pharmacy and Pharmaceutical Sciences, KNUST, Kumasi, Ghana and the School of Physical Sciences, University of Cape-Coast, Cape-Coast, Ghana; between December, 2013 and May, 2014.

Methodology: Preliminary phytochemical screening was carried out on the extract. Ammonium chloride-induced tracheal mucus phenol red secretion in ICR mice and the suppression of citric acid-induced cough in Dunkin-Hartley guinea pigs were determined after treatment of experimental animals with 100 mg/kg sodium cromoglycate, or 20 mg/kg dihydrocodeine respectively, as well as with 100, 250, or 500 mg/kg of the extract.  A 100, 250, and 500 mg/kg dose of the extract was administered daily for 28 days to groups of guinea pigs to establish a safety profile in a sub-chronic toxicity study.

Results: Phytochemical screening revealed the presence of saponins and cyanogenetic glycosides, alkaloids, and sterols. The extract significantly inhibited (P ≤ .01 - 0.001) tracheal mucus phenol red secretion, and suppression of citric acid-induced cough. There were no significant changes in body weight, haematological profile, as well as liver and kidney functions in the sub-chronic toxicity study.

Conclusion: The findings indicate that the ethanolic leaf extract of Polyscias fruticosa has muco-suppressant and anti-tussive properties, and is safe to use; hence a suitable adjunct/remedy for the management of asthma.
